Anti-polution device

ABSTRACT

An anti-polution device having a horizontal, cylindrical water filled housing connected to a pair of automotive exhaust pipes and to a pair of vertical cylindrical tubes each containing a filter medium and a propeller attached to a vertical rod passing into said filter medium. Each vertical cylindrical tube has a horizontal exhaust tube for expelling the remaining minute impurities. The exhaust fumes pass into the water filled housing and some of the impurities are removed. The partially cleaned exhaust fumes next pass into the filter medium of the vertical rods and are further cleansed. The propeller which is actuated by the air currents helps retain these fumes in the filter medium for a longer period of time before allowing same to pass out the exhaust tubes house causing greater cleansing of the fumes.

4 Claims, 5 Drawing; Figures ANTI-POLUTION DEVICE This invention relatesgenerally to an anti-polution device, and more particularly to ananti-polution device which can be attached to the existing dual exhaustpipes of a motor vehicle and prevent the harmful particles of combustionfrom escaping into the atmosphere.

In the past, various types of devices have been developed to treat theexhaust fumes of motor vehicles so that the fumes of combustion wouldnot be allowed to enter the atmosphere. Under certain meterologicalconditions, the exhaust gases of motor vehicles when discharged into theatmosphere combine therewith to form what is commonly known as smog. Inlarge cities, where the smog has a tendency to accumulate, it has becomea health hazard. None of the aforementioned devices have been found tobe completely satisfactory. It has been found that to have a filtermedia which will do an adequate amount of filtering, the compaction andcomposition must be of a fairly compact nature. If

the filter media is not compact enough, the amount of impurities trappedtherein becomes minute. If the filter media is compact pressure withinthe exhaust system of the internal combustion engine is not strongenough to force the exhaust gases through such a filter without thebuild-up of undesirable back pressures.

I the filter media 20. Integral with each tube 18 and set Therefore, aprincipal object of this invention is to provide an anti-polution devicefor connection with the exhaust system of a motor vehicle which willremove a substantial amount of the harmful elements found in the exhaustgases without interferring with engine performance.

Another object is the provision of an anti-polution device with a draftinducing means which forces the exdetailed description of the inventionand from the appended claims and drawings set forth herein below, inwhich:

FIG. 1 is a side view of a motor vehicle showing a preferred form of theinvention thereon;

FIG. 2 is a pictorial view of the first embodiment of the invention;

FIG. 3 is a sectional view in elevation taken along lines 3-3 of FIG. 2;

FIG. 4 is a top plan view as taken along lines 4 -4 of FIG. 3;

FIG. 5 is a partial side view of a motor vehicle showing anotherembodiment of the invention thereon.

Referring now more specifically to the drawings, the numeral 10generally describes the anti-polution device which may be seen morespecifically in FIGS. 2 through 4. The device 10 includes a pair ofexhaust pipe Mounts 12, which mate with the dual exhaust pipes 14. TheseMounts 12 are held securely in place by any known means, not shown, suchas thumb screws, etc. Integral i in a position above the level of thefilter media 20 is an exhaust pipe 30.

The embodiment shown in FIG. 5 illustrates a form which places theanti-polution device 10' in a position of less danger by being away fromthe highway level and the bumper area of the vehicle and also by placingthe propellers 22' in a position of more air flow. A pair of goose neckshaped mounting means 12' and provided to serve this purpose.

In operation, the exhaust fumes forced out of the motor vehicleexhaust'pipes, passes through a water bath which removes all soluableimpurities. The remaining impurities pass into the filter mediacontained in a pair of vertical tubes and are retained therein for aperiod of time during which a substantial portion of the non-soluableimpurities are removed. The minute amount of impurities are passed outthe exhaust pipes integral with the vertical tubes. The major force inretaining the gases for enough time in the filter media is accomplishedby the action of the propeller which is air actuated and its associatedvertical extension and the blades thereon which tend to'constantly mixthe filter media and circulate the gases therein for more removal ofimpurities. See the arrows in FIG; 4

for the flow of the gases abovementioned. v

I wish it to be understood that I do not desire to be limited to theexact detailsof construction shown and described, for obviousmodifications will occur to a person skilled in the art.
